Pilot Of Plane Crashed In Delta Identified As 22-Year-Old Man

A 22-year-old man killed when a small plane crashed into the delta just north of Antioch as Colin Um, of Berkeley, according to a Contra Costa County sheriff's spokesman.

Um's body was recovered around 5:30 p.m. Monday.

The crash was reported around 5 p.m. Sunday by a boater in the area who reported the plane had splashed down. Emergency crews responding to the scene were able to find a backpack and some other debris -- but the location of the aircraft was not immediately apparent.

Marine crews using sonar found it Monday morning. The victim was recovered later that evening. Investigators say Um was the only person onboard.

The plane is believed to be a Piper Cherokee that took off from Buchanan Field Airport in Concord.

The crash remains under investigation. Anyone who witnessed it, or has information relevant to the investigation, is asked to contact the National Transportation Safety Board by email at witness@ntsb.gov.
